Appologies to VC: I've tried nading water in quite a few different ways now (late nights lol) and I understand what you mean now, basically if your in or around water like aztec or courthouse (not enough to fully submerge yourself) and a grenade lands in the water, you will not take any damage. Although, if you are in deep water (lochs2) and nade underwater you will take the same amount of damage you would from a nade out of water at that range.
Sorry VC
'BUT MY AIM NEVER MOVED!!!': Shooting from a ladder? stood on a plant pot? or any other breakable/movable object?... no wonder your aim isn't quite as jolly as usual. Aiming is near impossible when in any of these situations, you can often shoot at point blank at an enemy on a ladder without hitting them... and with the latest update making it trickier to get off the ladders, you'll need a bit of practice dismounting. If the ladders are close to the ground, jump off and adjust your aim and fire away

If you dont have time, or are too high to get off the ladders... time for good old flashbangs, with you already facing a way you should take a little less of the flash (ignore the animation problems.... your holding onto a ladder with both hands... then use both hands to use the nade

) which is often enough to get you off the ladders.
Standing on barrels or breakable boxes (only the breakable ones) may offer a better view, but you aim as if your jumping in the air (which, unless you know where each stray bullet is going to go, can be a bit bad)
Say, for example, your using a breakable box to see over something and you see an enemy coming. Quickly duck, aim down, shoot the box, readjust your aim and your ready for some pwnage.
Fancy a quick rush love?: Rushing is actually quite skillful (please ignore this statement if you've ever witnessed a nub-rush on SBG)
Thanks to the all powerful Pug for taking me on his rushes on italy.
Tips for a succesful rush (single person): Two little tactics for a single person rush;
1. Pick a fast firing weapon, any will do (unsilenced m4 is my gun of choice for rushing) DONT STOP!!! at any cost during a rush do not stop... aim high and run AT your target, when you run your gun is less accurate so dont attempt to take them side on, just run at them and aim for the head, only takes one lucky bullet to kill an enemy. The enemy will be able to get a few shots on you, but unless they are a really good aim or a bit of a pro player, chances are they wont take into account you running at them and won't alter there aim enough to knack you.
2. This is my favourite form of rush at the moment as you can get several kills without emptying your clip or pistol (yes you can rush with a pistol). Pick a powerful weapon (deagle, burstfire glock, MP5) same as before... run at the enemy, but dont fire until your close to them, more powerful weapons can kill in one hit in the chest at close range

still best to aim for the head though... just to be on the safe side.
Tips for a succesful rush (two people): This was an old tactic me and pug used to do, became pretty special in the end lol. First person in the rush takes style one of the single person rush, second person takes style two.
Make sure you are running staggered but parralel (i.e. one infront of two, but slightly to the side of each other) that way you reduce your chance of team harming, also you allow your second person to shoot without having to wait for the first to die. The advantage of two people is, if one gets into trouble the second can help out, if one is caught by a camper, the second person has a better chance of finding them. first person rushes and does as much damage as possible, while the second player picks off the enemies from a safer distance.
I wouldn't advise rushing with more than 2, can lead to all sorts of tk-tastrophies, but if you insist, use the 2 people tactic, if number 1 dies 2 takes his place 3 takes 2's place, etc etc.
WANTED: Basically I need a volunteer to help me with some screen shots of camping positions, a few clever 'unreachable' places and a few map exploits (not cheats

)
Also: If you want anything explaining, or want to know how to do something better, just ask and i'll look into it as much as possible.
